Problems solved by technology

[0002] When the car is bumping or braking, the lights will have contact with the car body, which may cause damage to the lights in the long run
Therefore, this problem can be solved by adding shock-absorbing pads, but the existing shock-absorbing pads are generally ordinary rubber washers, and after a long period of use, rubber washers are prone to aging and seriously affect the service life

Abstract

The invention relates to a sealing gasket bar for an automobile lamp and a preparation method. The sealing gasket bar comprises an annular steel ring (10) with the outer surface being provided with aplurality of evenly-distributed hemispherical concave points, thermoplastic polyurethane elastic particles (20) fixed to the corresponding concave points, and a teflon shell (30) wrapping the particles (20). The sealing gasket bar has ultrahigh airtightness, elasticity and external toughness.

Description

technical field [0001] The invention relates to the field of vehicle lamp manufacturing, in particular to a gasket strip for a vehicle lamp and a preparation method thereof. Background technique [0002] When the car is bumping or braking, the lights will come into contact with the car body, which may cause damage to the lights in the long run. Therefore this problem can be solved by increasing the damping pad, but the existing damping pad is generally a common rubber gasket, and the rubber gasket is easy to cause aging after a long time of use, which has a strong impact on the service life. [0003] In view of the above-mentioned defects, the designer is actively researching and innovating, in order to create a new type of structure of the gasket for car lights and its manufacturing method, so that it has more industrial value. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a ...
